Etude foundation I bought with my own money

I have oily skin, so I'm most worried about pore coverage.

If you apply matte sunscreen followed by Etude Double Lasting Foundation, the coverage is great!!!

I've been using it because it doesn't cake much even in the summer if I apply a very thin layer. Since it provides such good coverage with just a small amount, I'm worried I might use it forever lol. It looks like it'll expire soon.
